The 12-, 13-, and 20-year-old were taken back to the resort side of the shore, while the 11-year-old was taken to the beach side, leading to some tense moments when officials on the shore side believed that the 11-year-old was still missing, according to Boghdan.

The 11-year-old and 20-year-old were transported to Cape Cod Hospital with injuries that were not considered life-threatening, said Boghdan.

The swimmers’ parents were not at the scene but were notified and went to the hospital, said Boghdan. Boghdan said he wasn’t sure of the four’s exact relationship.
